SNAP-HOOK.

SPECIFICATION formingpart of Letters Patent No. 224,856, dated February 24, 1880.

` Application led December 18, 1879. i l

. 1o the tongue, and to the combination of said post with the other parts.

In the accompanying drawings, Figure 1 is a front elevation of a snap-hook which embodies my invention. Fig. 2 is a side eleva- Fig. 3 is a front elevation of the body of the snap-hook Without the tongue, and With the end of the hook proper turned to one sidein the position in which it Was cast, and Fig. et is` a side elezo vation of the saine, together with the tongue,

represented as being inserted in place.

A designates the body of the hook; a, the

hook proper formed thereon. hook is cast with a spring-receiving recess upon its under side, as shown in Fig. 2, and with an opening extending through the body for the insertion of the tongue, as shown in Fig. 3. Transversely to this opening, and inone and the same piece with the body of the snap, is

3o an axle-pin, b, and in front of this opening is a rigid post, 0.

-The body ot' the" tongue B is offset or crooked near its rear end, as shown in Figs. 2 and 4, back of which offset there is a pad, d, which furnishes a seat for the spiral spring e. Upon the front of this offset is a small arm, a, which, with the body of the tongue, forms a recess to receive the axle-pin b. The tongue also has an y opening between its two ends, into which the 4o rigid arm c iits when the tongue is in place.

As in ordinarysnap-hooks, the hook proper,

c, is cast when turned to one side, as shown in Figs. 3 and 4C. After the castings are obtained the tongue is inserted through the opening in the body of thesnap-hook, as shown in Fig.

The body of theV cess and seated upon the pad d, When the 5o` tongue is turned forward, so that the post enters the opening in it and the tongue rests upon the body of the snap-hook. The hook proper is then straightened up into its proper position, as shown in Figs. l and 2, so as to act upon the tongue and prevent it from being turn'ed backward and Withdrawn, thereby completeiy and efficiently securing the parts in place without any riveting Whatever.

The rigid post c prevents the tongue from 6o being Wrenched sidewise, and thereby rmly supports said tongue. It also prevents a ring which is received by the snap-hook from being crowded so far up under the tongue :as to obtain a Wedgin g ei'ect,Which would have a tend- 65 ency to pry or bend the tongue out of place. I am aware that a prior patent shows a snaphoolr with the axle-pin extending across a recess in the body of the snap-hook, and With a tongue having an offset body and aXle-pin- 7o receiving recess, back of which recess was a spring-pad and spring,land I hereby disclaim the same.

I claim as my inventionl. The combination ot' the body ofthe snap- 75 hook having a rigid axle-pin, the tongue B, having an aXle-pin-receivin g recess, open upon its front side, and the rigid post c, formed on the body of the hook and passing through the tongue, substantially as described, and for the 8o purpose specified.

2. In a snap-hook, the rigid post c, formed on the body of the hook, in combination with the tongue having an opening whiolrreceives said post, substantially as described, and for the purpose specified.
